1* Marvell PXA1928 Clock Controllers
2
3The PXA1928 clock subsystem generates and supplies clock to various
4controllers within the PXA1928 SoC. The PXA1928 contains 3 clock controller
5blocks called APMU, MPMU, and APBC roughly corresponding to internal buses.
6
7Required Properties:
8
9- compatible: should be one of the following.
10  - "marvell,pxa1928-apmu" - APMU controller compatible
11  - "marvell,pxa1928-mpmu" - MPMU controller compatible
12  - "marvell,pxa1928-apbc" - APBC controller compatible
13- reg: physical base address of the clock controller and length of memory mapped
14  region.
15- #clock-cells: should be 1.
16- #reset-cells: should be 1.
17
18Each clock is assigned an identifier and client nodes use the clock controller
19phandle and this identifier to specify the clock which they consume.
20
21All these identifiers can be found in <dt-bindings/clock/marvell,pxa1928.h>.
